Inventory item cost price update

Guys,

Would like to check, i am running weighted average inventory costing method.

I run inventory closing month end to re-calculated my weighted average inventory cost. 

I would like to ask, after my inventory closing, will my weighted average cost updated into my item cost price form as below?

I have check it will not updated into the item cost price form. Wonder is there a parameter to turn on or how can i achieve to update my month end weighted average cost into the item cost price form
